Enlarging post holes?

[Shenaniganizer]

How would I go about making the diameter of the post routs larger on my Jackson Kelly?

I mean the holes where the posts mount into for Floyd Rose bridges.




Like this:

Where those holes are, around the rectangular rout.

A larger drill bit, preferably mounted on a drill press.

You have to get them just about perfectly level, or else the trem won't keep tune properly.

Also, be sure to make them big enough to have to really force the bushings for the trem posts home. You want those posts to be VERY solid.

I want to say they'd fit with a bit of a forceful push, but I'm afraid of messing.. uh, something, up. I dunno what I'd mess up, though.
